The exercise I am doing is to make an interface of a theater which contains 5 rows and 5 seats or chairs. the user can make a series of actions between which they are Book, Release and Buy ("R", "L" and "V").
Well the problem is this: when choosing the action either "R", "V" or "L", the arrangement is modified but only the first time, the second time it restarts again, what I want is that for each action you choose, those new actions or states that this user adds are saved.
The way in which you are going to modify and create the fix should only be with PHP and without using global variables since in the exercise I am doing this is specified. Your opinions would be very helpful thanks.
